Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed April 4, 1906. Serial No. 309,811.

T0 all whom, t may concern:

Be it known that 1, CHAELEs S. UPToN, a citizen of the United States, and a resident of Walla Walla, in the county of Wallawalla and State of Washington, have invented certain new and useful Improvements in Co'lters and Stubble-Turners, of which thev following is a specification.

My invention is an improvement in colters and stubble-turners for plows; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view, partly in section, of my improved device, the lower box for the bearing of the colter-shaft being detached and shown partly in section for purposes of illustration. Fig.. 2 is a top plan view of the improved devices. Fig. 3 is a rear elevation thereof. Figs. 4, 5, and 6 are detail views of the clamp for securing the colter-standard to the beam, and Fig. 7 is a detail view of the colter-shaft.

The colter-standard A is cranked at its lower end A and is in practice secured to the plow-beam B by means of a suitable clamp O, which clamp may be designed to accommodate itself to any ordinary plow-beam. The clamp O has an upright tubular portion C and a set-screw C2 operating in connection therewith, whereby to secure the shaft A in any suitable adjustment within the clamp O, as will be understood from Figs. 1 and 4 of the drawings.

The colter D, shown as a disk colter, is journaled, as presently described, in the arms E and E2 of the fork of the colter-support E, the latter having at its front end a sleeve E3,

`secured upon the cranked lower end of the standard A by means of the collar F, and the set-screw F, as will be understood from Fig. 1 of the drawings.

The colter-support has its arms E and E2 provided with bearings for the shaft D of the colter D, the said bearings being preferably provided with the lower caps G, adapted to receive the Babbitt metal G and secured to the fixed caps Gr2 by means of the bolts G3, as shown in Fig. 1. By this means the caps may be readily removed for repairing the colter, renewing the Babbitt metal, or for any other desired purpose. The disk D is provided with the hub-sections D2, riveted together and to the disk and keyed upon the central portion D3 of the shaft D, so the colter-disk and its hub will revolve with the turning of said shaft D within its bearings in the colter-support. One o f the arms of the colter-support is provided in rear of the bearings for the colter-shaft with an eye E, having a vertical opening for the upright shaft H of the carrier-bar H for the stubble-turner I an'd a set-screw E5 for securing the shaft H l in any desired adjustment within the eye E4. By this means the stubble-turner may be adjusted vertically or laterally with respect to the colter and be secured in any desired adjustment relative thereto.

The stubble-turner I is bolted or otherwise suitably secured to its carrier-bar and is an approximately diamond-shaped steel sheet with proper curves to follow the colter D and is symmetrical, as best shown in Fig. 1, so that when it is dull or Worn it can be reversed.

I claim- 1. The improvement substantially as herein described, comprising the cranked standard, a clamp for securing the same to a plowbeam, a colter-support having at its front end an upright sleeve fitting on the lower end of the cranked standard and having the rearwardly-projecting fork-whose arms are provided with bearings for the colter-shaft, and one of said arms being provided in rear of its bearing with an eye having a vertical opening, and a clamping-screw intersecting said. opening, the colter having its shaft journaled in the bearings of its support, a stubbleturner consisting of a symmetrical reversible plate and a carrier-bar to which said stubbleturner is secured, said bar being provided at its front end with an upright shaft fitted and secured within the eye at the rear end of the colter-support, all substantially as and for the purpose set forth.

2. The combination with the colter and the fork supporting thesame and having one of its arms provided with an eye having an upright opening and a clamping-screw intersecting the same, of a stubble-turner and its carrier having at its front end an upright shaft secured in the said eye and adapted for vertical and lateral adjustment, substantially as set forth.

3. The combination of a colter-support having a rearwardly-projecting fork whose IOO arms are provided with bearings for the oolits front end With an upright shaft fitting and ter-shaft, one of said arms being provided secured Within the vertical eye ofthe eolterin rear of its bearing with a vertical eye, a support, substantially as set forth.

clamping-screw intersecting the opening of CHARLES S. UPTON. said eye, a colter journaled in the said bear- Witnesses: ings, a stubble-turner, and a oarrier-bar sup- H. S. BLANDFORDl porting said stubble-turner and provided at EDWARD C. MILLS.
